Abstract
The upcoming generation of 4-meter solar telescopes (such as DKIST and EST) and planned networks for synoptic solar observations (such as SPRING) will rely on full Stokes spectropolarimetric measurements to infer the properties of the solar atmosphere. They will produce a wealth of data whose analysis represents a formidable challenge. To solve this problem, we have pursued two approaches within the H2020 SOLARNET project: parallelization of a Milne-Eddington Stokes inversion code for use in mid-size servers and implementation in graphics processing units (GPUs). Here we present the results of those efforts. P-MILOS and G-MILOS are two Stokes inversion codes that can be used to produce maps of physical quantities in real time during the observations at the telescope, or to generate science-ready data from time series of spectropolarimetric measurements taken by both imaging and slit-based spectropolarimeters. These codes will open a new era in solar research.
